Do you have a cracked injector line? Or maybe you've got a 5.9L Cummins and you're converting your rail, lines, and tubes over to the larger 6.7L components and need a full set of lines. Whatever the reasoning, these lines from Fleece Performance are a great option, available individually or as a complete set. Please note that lines 2 and 3 are identical, as well as 4 and 5. If you need more than one line, but not the complete kit, just add to cart the ones you're after.
